A process in which force is generated within muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis.

The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in skeletal muscle.

Self-propelled movement of a cell or organism from one location to another.

The process whose specific outcome is the progression of the extraocular skeletal muscle over time, from its formation to the mature structure. The extraocular muscle is derived from cranial mesoderm and controls eye movements. The muscle begins its development with the differentiation of the muscle cells and ends with the mature muscle. An example of this process is found in Mus musculus.

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

The orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work.

The process whose specific outcome is the progression of the adult somatic muscle over time, from its formation to the mature structure.

The specific movement from place to place of an organism in response to external or internal stimuli. Locomotion of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions.

The specific movement from place to place of an organism in response to external or internal stimuli. Locomotion of a whole organism in a manner dependent upon some combination of that organism's internal state and external conditions.

The deposition of eggs (either fertilized or not) upon a surface or into a medium such as water.

Formation of myofibrils, the repeating units of striated muscle.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a filament composed of myosin molecules.

The process in which a relatively unspecialized cell acquires specialized features of a muscle cell.

Any process that modulates the frequency, rate or extent of the formation of a bipolar filament composed of myosin II molecules.

The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.

Any process that activates or increases the frequency, rate or extent of ovulation, the release of a mature ovum/oocyte from an ovary.

Self-propelled movement of an organism from one location to another through the air, usually by means of active wing movement.

The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in striated muscle.

The dark-staining region of a sarcomere, in which myosin thick filaments are present; the center is traversed by the paler H zone, which in turn contains the M line.

Bipolar filaments formed of polymers of a muscle-specific myosin II isoform, found in the middle of sarcomeres in myofibrils.

A swelling at a site along the length of a polytene chromosome, thought to be the site of active transcription.

A filament of myosin found in a muscle cell of any type.

Bipolar filaments formed of polymers of a muscle-specific myosin II isoform, found in the middle of sarcomeres in myofibrils.

Bipolar filaments formed of polymers of a muscle-specific myosin II isoform, found in the middle of sarcomeres in myofibrils.

The repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

The dark-staining region of a sarcomere, in which myosin thick filaments are present; the center is traversed by the paler H zone, which in turn contains the M line.

A cardiac myofibril is a myofibril specific to cardiac muscle cells.
